I'm a big fan of Andy at Vintage Tube Services too, and have bought from many of the usual suspects. Most tubes that are marketed as NOS are not- they are old tubes, "pulls," that come out of other equipment. Finding true "never used" old tubes is a challenge. Brent is good and will stand behind his product- you should read his page on NOS as well.
